Answer:
The first deal is better because it has more balloons for not too much of a price (individually)
Step-by-step explanation:
15*4= 60
60/18= 3.33
Deal 1= 3.33 for each balloon
10*5= 50
50/16=3.125
The answer is: " 1024π units² " ; or; " 3215.36 units² " .
______________________________________________________
A = π * r² ;
A = π * 32² = 1024 π units² ;
or, using "3.14" for "π" ;
1024 * π = 1024 * (3.14) = 3215.36 units² .

Answer:
a = 6/5
b = 7/8
c = 1/5
Step-by-step explanation:
We want to make two of these equations be in terms of the same variable, so let's solve the first and third in terms of b.
5a-24b=-15 -> -3 + 24b/5 = a
48b+35c = 49 -> 49/35 - 48b/35 = 7/5 - 48b/35 = c
Now we can replace the a and c in the second equation and solve for b.
10a+45c=21
10(-3+24b/5)+45(7/5 - 48b/35) = 21
-30 + 48b + 63 - 432b/7 = 21 -> -12 = -96b/7 -> b=7/8
Now we can plug b back into the other two to solve for a and c. I will leave that to you unless you would like the steps there.
